Vehicle-mounted curved rail lubricant lateral spraying device

Abstract

The invention discloses a vehicle-mounted curve rail lubricating agent lateral spraying device. The vehicle-mounted curve rail lubricating agent lateral spraying device comprises a height position adjusting pipe and a lateral spraying nozzle, wherein the height position adjusting pipe is fixed to a rolling stock axle box; a horizontal adjusting pipe is arranged in the position, close to the end portion, of the horizontal part of a bent pipe and can be adjusted in the axial direction on the horizontal part of the bent pipe; the horizontal adjusting pipe is connected with a vertical positioning sleeve of a round pipe structure; a positioning groove is formed in the lateral wall of the upper portion of the vertical positioning sleeve; an axial positioning pipe is arranged in an inner hole of the vertical positioning sleeve; an oil spraying pipe is arranged inside the axial positioning pipe; the upper end of the oil spraying pipe is connected with a petrol pump; the lower end of the petrol pump is connected with the lateral spraying nozzle; a spout of the lateral spraying nozzle corresponds to the elongation position of an outer rail of a curve rail; a radial positioning pin is arranged on the outer wall of the positioning pipe and matched with the positioning groove. The friction stressed portion is accurately and effectively lubricated and coated, abrasion of the friction portion is reduced, the service life of the rail is prolonged, consumption of lubricating materials is reduced, and waste is reduced.

Description

technical field [0001] The invention relates to the technical field of railway rail lubrication coating equipment, in particular to a vehicle-mounted curved rail lubricant side spraying device. Background technique [0002] The vehicle-mounted curved rail lubricating coating device in the prior art is placed at the tail of the railway passenger train, and lubricating materials such as lubricant or grease are applied to the corners of the outer strands of the curved rail to achieve the contact between the wheel rim of the rolling stock and the rail. Lubricate and reduce friction on the frictional force surface, reduce the wear of the contact surface, and prolong the service life of the rail. With the continuous increase of the running speed of the train, in the prior art, the lubricant or grease is sprayed obliquely from the top of the rail The method can no longer meet the actual requirements of rail lubrication. When the nozzle is installed too high, the lubricant will be s...

[0002] The vehicle-mounted curved rail lubricating coating device in the prior art is placed at the tail of the railway passenger train, and lubricating materials such as lubricant or grease are applied to the corners of the outer strands of the curved rail to achieve the contact between the wheel rim of the rolling stock and the rail. Lubricate and reduce friction on the frictional force surface, reduce the wear of the contact surface, and prolong the service life of the rail. With the continuous increase of the running speed of the train, in the prior art, the lubricant or grease is sprayed obliquely from the top of the rail The method can no longer meet the actual requirements of rail lubrication. When the nozzle is installed too high, the lubricant will be sprayed on the top surface of the rail, causing the locomotive to slip or the train stops; When the speed is too low, the lubricant is sprayed below the contact zone between the wheel rim and the rail. The lubricant does not have the effect of lubricating and reducing friction, which not only causes lubricant waste, but also pollutes the rail and track bed
